New N-methyldiethanolamine-modified metal alkoxides were synthesized and employed as sol–gel precursors to obtain atomically dispersed catalysts with high surface area tunable acid–base properties.

An iced lipid nanotube has been employed as a template to perform sol-gel transcription of transition metal alkoxides in the absence of solution catalysts, giving titania, tantalum oxide and vanadium oxide nanotubes in aqueous dispersions.

A general and convenient method for the stereoand regiospecific synthesis of conjugated alkadienes, alkenynes, arylated alkenes, and other olefinic compounds is described. The reaction of (E)or (Z)-lalkenyldisiamylboranes, or 2-(E)-l-alkenyl-l ,3,2-benzodioxaboroles easily obtainable by hydroboration, with either (E)or (Z)-l-alkenyl halides in the presence of a catalytic amount of tetrakis(trip...

A new class of bimetallic isopropoxides of nickel(II) with niobium and tantalum with the general formula, Ni[M(OPr')6]2, (where M = Nb or Ta) have been synthesized by the reaction of nickel chloride isopropanolate, NiCl2-A:Pr'OH, with potassium hexaisopropoxy metalates, KM(OPr')6, (M = Nb or Ta) in the molar ratio 1:2. These derivatives have been characterized by elemental analyses, molecular w...

Metal alkoxides are easily available and versatile precursors for functional materials, such as solid catalysts. However, the poor solubility of metal in organic solvents usually hinders their facile application sol–gel processes complicates access to complex carbonate or oxidic compounds after hydrolysis precursors. In our contribution we have therefore shown three different solubilization str...

Atriblock copolymerof polystyrene-polybutadiene-polystyrene (KratonD1102)hasbeenused topattern barium titanate precursor with nanoscale modulations. The copolymer self-assembles to yield cylindrical polystyrene nanodomains in a polybutadiene matrix. The preorganized thin films of polymer are then selectively OH-functionalized in situ on the unsaturated carbon bonds in the polybutadiene matrix w...

Highly crystalline metal oxide nanoparticles such as CoO, ZnO, Fe(3)O(4), MnO, Mn(3)O(4), and BaTiO(3) were synthesized in just a few minutes by reacting metal alkoxides, acetates or acetylacetonates with benzyl alcohol under microwave heating.

Deacetoxylation of the oxo-centered triruthenium acetate cluster by acetyl chloride or triethylsilyl chloride led to the formation of a versatile precursor [Ru(3)O(OAc)(5)(Cl)(4-methylpyridine)(2)(CNt-Bu)], whose chloro ligand was readily substituted by other bridging ligands, i.e. alkoxides, carboxylates or sulfides.
